[Also in Divisions G1 and H2] In an apparatus for measuring biopotentials or bioimpedances where conductive electrodes are applied to a patient's skin, a system to prevent a hazardous level of current flow into the patient is included. Transistors Q 4  and Q 5  are connected in series between positive and negative power supplies 23, 24, respectively and the patient, which transistors are turned on by transistors Q 6  and Q 7  respectively, so that in the event of failure of either power supply, both supplies are isolated from the patient. In addition, to protect the patient from excessive base currents from terminals 10, 11 of transistors Q 1 , Q 2 , diodes D 1 , D 2  of opposed polarity are connected between the collector terminals. This arrangement prevents saturation of either transistor in the event of failure of the other since the diodes clamp respective collector electrodes to the potential of the other. Each of the transistors Q 1 , Q 2  may be replaced by a Darlington pair.

Abstract: 1365795 Data display apparatus; matrix displays; indicating purchase items and change INTERNATIONAL BUSINESS MACHINES CORP 21 Nov 1972 [20 Dec 1971] 53668/72 Headings G4H G4T and G5C Data character display apparatus comprises an array 14 of light emitting devices which form segments of characters to be displayed, strobe means for intermittently energizing the segments so that they emit light pulses, a probe 13, sensitive to the light pulses, for tracing over selected segments to trace a selected character, and control circuitry responsive to the output from the probe for continuously energizing the selected segments so that the array displays the selected character. The segments which comprise light emitting diodes, are sequentially energized via OR gates 20 and a counter 40 which receives clock pulses from an oscillator 32, the light pulses emitted by the segments being invisible to the human eye but detectable by the pen 13. As the pen traces over selected segments of the array 14, the video signals from the pen are fed via an amplifier 26, a threshold circuit 28 and an AND gate 24 to a shift register 38. The data stored in the register 38 is fed to a static register 45 the output of which causes continuous illumination of those segments traced by the probe. The output of the register 45 is also supplied via a decoder 49 to a central processing unit 12 when a TRANSMIT switch is closed. If a displayed character is not verified as correct by the operator, an ERASE switch may be closed to reset the registers 38, 45. The unit 12 sums the numerals traced by the pen in arrays 14, 16, 18 and enables the display of a total on the tablet 10. The operator traces over segments of arrays on the tablet 10 corresponding to the payment made by a customer and the unit 12 causes the display in arrays labelled CHANGE of the change to be returned to the customer.

In a bag making and filling machine of the type wherein a tube, formed from a web, is pulled through the machine by jaws which effect a transverse seal, the reel, from which the web is fed, is itself driven to obviate the effects of inertia. In the form shown, a web feed reel 2 is driven by a rubber covered roller 7 which bears upon its periphery. The shaft 6, Fig. 2, which carries the roller 7, is driven via chains 4, running on sprockets 8, from reciprocating jaw carriage 3. When the jaws begin their downwards stroke to seal and feed the web, magnetic clutches 9 engage to transmit drive to roller 7. When the jaws reach their lowest position the clutches disengage and the wheel is braked pneumatically. If the wheel overruns an arm (not shown), sensing the lack of tension, actuates means for rotating the reel to take up slack.

[Also in Divisions G2-G3] In an automatic focusing device for use in correcting the focus of a cine or film-strip projector when the film "pops" due to heat, the distortion of an area of film 17 in the projection aperture 19 is determined by detecting means located to monitor an area of film outside the projection aperture The detector means may comprise:- a) A pneumatic system to which air from pump P is blown on to film 17 through a nozzle 32 whereby a back-pressure builds up. Any change in this pressure, due to "popping" is measured by a bellows 40 in the air-line, expansion or contraction of the bellows shifting a frame 47 which, through a lever-arm reduction, shifts by a small amount, the projection lens 26 by swinging the mounting frame 44 about pivots at 45. In another form the nozzle and air-line are slidably mounted while the bellows is attached to a fixed point; in this case the nozzle moves to maintain a constant pressure in the bellows and in so doing shifts the lens. b) The pressure changes are measured using a light float member in an air chamber, movement of the float being detected by the charge in inductance which is made to actuate an electrical servosystem to move the lens. c) Film "popping" may be detected Fig. 3 (not shown) by receiving a beam of light from the area outside gate 19 between two photo-cells whose output when the beam shifts is used to drive a reversible motor rotating a cam which shifts the film mounting or lens. d) Some film distribution is proportional to its temperature, the film temperature may be measured by focusing infrared radiation on to a photo-cell whose output actuates a solenoid shifting the lens; Fig. 4 (not shown).
